2. The method of claim 1 wherein M<N.
3. The method of claim 2 wherein N≥2.
4. The method of claim 2 wherein N≥3, and M≥1.
5. The method of claim 2 wherein N≥3, and M≥2.
6. The method of claim 1, wherein the CSI comprises an identity of each NZP CSI-RS resource in the selected preferred subset.
7. The method of claim 6 wherein, for each NZP CSI-RS resource in the selected preferred subset, the identity of the NZP CSI-RS resource is an index of the NZP CSI-RS resource within a set of NZP CSI-RS resources configured for the wireless device.
8. The method of claim 1, further comprising receiving an indication of a restriction from the base station.
9. The method of claim 1, wherein the selected preferred subset corresponds to a preferred subset of the N TRPs for a downlink transmission to the wireless device, wherein the downlink transmission is one of Non-Coherent Joint Transmission, NC-JT, a Dynamic Point Selection, DPS, transmission, or a diversity combining transmission.
10. The method of claim 1, wherein the selected preferred subset is for any one or any combination of NC-JT, DPS, and diversity combining.
11. The method of claim 1, wherein reporting the CSI comprises sending a CSI report comprising a first part and a second part, wherein a size of the selected preferred subset is encoded in the first part.
12. The method of claim 11, wherein the first part has a predefined payload size, is encoded before encoding the second part at the wireless device, or both has a predefined payload size and is encoded before encoding the second part at the wireless device.
